Vega, 17.11.1 vs blockchain driver performance

On Vega 64 I noticed that 17.11.1 drivers have slightly better performance on Dagger-Hashimoto compute (using Claymore) compare to the august beta block chain drivers because we can increase memory speed over 1100mhz , that's interesting to see... but when computing CryptoNight (using Stak XMR, SGminer or CastXMR) the beta blockchain is still a lot faster. So I guess not all beta blockchain features are implemented?

I discussed with the CAST XMR developper and he told me that RX Vega compute mode is still missing from the 17.11.1 driver... is their any plan to add support for compute mode on the RX Vega anytime soon?

I would also like to know what is missing from recent drivers. Eth is faster and a lot more stable/almost roxk solid even in extrem dual mining scenarios with 17.11.x drivers. But xmr is "only" 1.3-1.4k with 17.11.x. With blockchain beta drivers i can get easy 2k and even more but stability is really really poor with blochain driver in OC scenarios. Even reference clocks are unstable with that old driver. Tried xmr-stack and with cast-xmr.

I also don’t understand why AMD dosen’t include the Blockchain drivers VEGA performance features in 17.11.x. Cryptonight algorithm use for XMR or Electronum mining is very slow compare to the beta drivers. We bought hundreds of Vega 64 and I feel we are left over...

If that were the case then the Blockchain Beta drivers would not be such a significant amount faster than any others in tasks like cryptonight. Clearly either a toggle is still required for Vega (or it would achieve the same hashrate in cryptonight as the BB driver), or you need better driver developers.

Please, after decades of pitiful driver releases, don't try to sell us the story that your driver engineers actually know what they're doing first time around.
